uint16_t idVendor;
uint16_t idProduct;
uint16_t bcdDevice;
uint32_t StrDescPtr;
uint8_t InReportCount;
uint8_t OutReportCount;
uint8_t SampleInterval;
void (*InReport)( uint8_t src[], uint32_t length);
void (*OutReport)(uint8_t dst[], uint32_t length);
} HID_DEVICE_INFO;
MemorySize Memory size in number of bytes
